Specification of Letheis Patent. Application filed January 15. 1906. Serial NollfifiCQZ:

To all who/n if may concern:

Be it knowther i EVERETT GoLDTH WAIT; :1 citizen of the U1 it eal States of America, and. a resident of El [lira ,the county of Elk-- hart and State oi Indians, have invented certain new and useful l!nproi eitnenrs in Coin- Controlled Brushinghlachines, of whieh the foilowing is a specifics tion My invention relates to brushing machines and has for its object improX-en'ionts in de vices of that kind.

More particularly my invention intends to provide a power driven brush which may he started into operation by means of a coin, end which after having run a cert-sin predotermined length of time will automatically come to s stop.

in the accompanying drawings a side elevation with part. of the casing hroken'avqsy so as to expose the inner Working mechanism; Fig. 22 is an elihirgerl elevation of the coin-acme ted contact springs and their associate; perils: Fig. 3 is a section oh lineof Fig. 4; P1, -3- is an elevation of the Wheel which comrols the electrical circuit after a. coin. has been deposited iii the machine and F 5 is o diagram oi the electrical circuits used.

In the accompanying drawings A is a. base plate upon which is mounted casing B for mclosing the operating mechanism. This casing is made in awe halves, being; divided 1 longitudinally and so zirmnged that the coin chute extends through one of the halves and may be connected to the inner mechanism. before the other half is secured in place. ease ccurecl at a cori'vel'iicnt place on the plate A amotor M which c '1 gears M to a shaft M s11 pported in (l. The shaft M extenels through an opening in the front part of tie C"! 11;: B en fl earries on. its end a brush D. men the motor is set into operation it causes :1 rotation of the brush. A shield B ower the brush 7) serves to both protect the brush and also to secure the two halves of the casing B mgetherattheir'upper ports. 11 pair 0;? E connect the shaft Iv 3 to e worm h which engages a Worm not she W11. shaft 1, Whirh carries ii WOZD] gear. on its outer end i s ii v h igure 1 is lend make electrical The points engs e I on the disk H and oonse electrical connection. The casing into which 2 v cross pipes hi the machine. is provided i l slot coin ehute L e; pipe K to e bloelr L mdireetly over the dis which serves as springs J. Supported at s, COIUPDiG oi the standards C, i magi. with an armature love I circuit at P for more inagnet- P is act's break the circuit ceases to flow rl'irou manner fs'iilffll t ranged is shown in ii which Q are two li'i place to the mes; eoizi to ciose e. the springs J. coin, are connected to parts by wire-s es shown. connected to trieity.

In normal notch H in line between Lilufil these springs are not in elect with each other. in this dropped through t2 the notch If h plsr i h with eecl' leaf? post Q, i one spur D spring, and

the other or the more? Bi orems he motor .i

opera ion of between the springs J and permits it to fall into a coin receptacle beneath the (llSk B. As the coin is being pushed from between the springs J the body of-the disk takQSdtS place as-the means of completing and maintaining the electrical circuit through the magnet P. This condition continues until the motor has run long enough to cause the notch H in the lisk H to come again to the springs J. When his occurs the circuit is broken through the znagnet P, and this in turn permits the spring P to move the armature P so as to brea the electrical connections for the motor at P. This brings the mechanism to'a stop with the disk H so located that the notch H is between the springs J. As before described, this is the normal position and one in which the machine is ready for the reception of another coin.

The motor is one of the ordinary kindwhich runs at or near a certain definite num-.

ber of revolutions per-minute. The. disk H and its cooperatin parts are so arranged that upon the disc making one complete rotation, after being started, the mechanism comes automatically to a stop. 'And the' gearing between the motor and the disk is so arranged that the motor will make some pre determined number of revolutions to one rotation of the disk. As a consequence, the result of dropping a coin into the openin at the top of one of the sta'ndardspr 1pipes is to cause the brush D to be rapid y-rotated for some redetermined period of time.

What I claim is 1. In a brushing machine, the combination with a motor, of a coin chute, a disk at the inner end of the coin chute and. provided with a notch for receiving a coin placed within said chute, an electrical connection closed by as coin when. within said notch, means by which the closing of said electrical connection will cause the motor to start into operation, and connections from the motor to the disk foricausi'ng the rotation of the.

' latter to remove th coin from its position I for making said/cl ctr cal connection, said disk and said electrical connection being so arranged that the disk will hold the electrical connection closed/after the coin is removed but permit the breaking of said connection upon a predetermined movement of saidmotor.

2. In abrushing'machine, the combination with a motor, of a casing containing the motor, a standard consisting-of a pipe extending upward from the topof the casing and having a coin slot at'its' upper-end, a

coin chute within saidpipe andexte'ndmg to the interior of the casing, a notched disk within. the casing and arranged to receive and support a coin passing-throu h said chute, contact springs placed in e ectrical connection with each 0t I er by a coin so su ported, means which the electrical con- I nection so closed will cause the motor to be started into operatiomand connectioi'ls from the motor to the disk for causing a movement of the latter to remove the coin from its contact closing position.

3. in a brushing machine, the combination with a motor, coin operated devices, and an inclosing case, of a standard formed ol" pipes and rising from the upper part of said case, and a coin chute extending through one of said pipes to the coin operated devices in the interior of said case.

4. In a brushing mag-lune, the combination with a motor, of a chute through which a com may be deposited within the machine, a

disk provided with a notch adapted to re-' ceive a coin so deposited, contact. springs on each side of said notch and arranged to be.

- electrically connected to each other through a coin resting in said notch, means by which the closing of such electrical connection will set the motor into operation, and connections from the motor to the dislcfor rotating the latter so as to remove the chill from between H said springs 5. In a brushing machine, the combination with a motor and an inc-losing case, of a coin chute extending to the interior of the case, a notched disk within the case and arranged to receive and support a coin )assing through said chute, contact springs. iaced in electneal connection with each 0t er by a coin so supported, means by which the electrical connection so closed will cause the motor to be started into operation, and connections from the motor to the disk for causing a movement of the latter to remove the coin from its contact closing position.

6.. Inna brushing machine, the combination with a motor, a magnet for starting it into operation, and a normally open circuit for said magnet and arranged to be closed by a coin de osited within said. machine, of a rotatable eviee arranged to primarily hold a deposited coin in a position to close said circuit, and connections from the motor to the rotatable device for rotating it soflas to remove the coin from its circuit-closing position, said rotatable device being so arranged that it will hold the circuit closed after the coin 'is removed.

v7. In a brushing machine, the combinacircuit-closing position and secondarily to controlsaid circuit after such removal.

'; I 8. The combination with a motor, a'n.elec- I cfoin tricaljeonneetion for the motor,*and. a

chute, of means by which a coin deposited in said chute will cause the closure of the circuit for themotm', and devices [or removing the coin from the position in which it causes the closure of the circuit innnediately after the starting of the/motor, said coin removing devices being so arranged as to hold the electrical connection closed after the removal of the coin.

9. The combination with a motor, an electrical connection, and a coin chute, of means by which a coin placed in said chute closes said circuit, and means for removing the coin from its circuit closing position, said coin re.- niovine' means serving also to hold the. circuit closed after the removal of the coin.

10. The combination. with a motor, and a coin chute, of a disk located at the end ofthe chute and ])l()\"l(l8(l ,\r'itl1 notch adapted to receive a coin, a pair of contact springs located on opposite sides of the disk but not normally. in electrical connection therewith,-

an electric circuit connected to said springs and normally open thereat, said springs beln'g so located that a com deposited in said notch closes the electrical connection be-- tween said springs, and means by which said motor is started into operation upon the closure of said connection. 1], The combination with a motor, of a circuit for said motor, means by which the circuit for said motor will be closed upon. dcpositing a coin within a chute, a chute for re- ,cciving' the coin, and means controlled by the motor for removing the coin from the position in which it causes such closure of the circuit, said coin removing means serving also to hold the circuit closed after the removal of the coin and until the motor has made a predetermined number of revolutions.
